Left Bundle Branch Block

[Jules619]

Is Left Bundle Branch Block considered congential heart disease if it is something I was born having?

For an insight into heart contractility:  Left bundle branch block (LBBB) is when there is a defect in the left bundle branches (located on the wall (septum) that separates lower heart chambers) that convey electrical signals to the ventricles; if the defect is in the right bundle branch, it is called right bundle branch block (RBBB).

Defect can be due to a prior heart attack, viral, drugs, etc. that damage septum cells  or it can be congenital.  It could be medically insignificant or significant.  Not uncommon to have skipped heartbeats or a double beat due bundle branch block.

I'm writing you about this LBBB because you seem to know all about it.  My girlfriend was diagnosed with it and has been prescribed coreg 3.125 twice a day.  This med has caused her to go up in pants size from an 8 to now a 12.  She's getting really upset over this and so I'm asking you if there is something else out there that does the same t hing as coreg but doesn't make a person gain weight?
thanks for your time......
